I also saw this relative/absolute flaw. But isn't it also a necessary/sufficient flaw that answer choice A suggests? Having a higher blood pressure is a necessary condition for being diagnosed with HBP, but it alone does not guarantee (or being a sufficient condition for) HBP.

Unless some people diagnosed with high blood pressure already have a base line blood pressure above the HBP threshold (no increase required), answer choice A may still have some merits.

I'm interested in joining as well, if that'd not be too late! I've taken the LSAT numerous times before and I'd love to contribute in any way I can. Planning to re-take in January.

I picked C too during my BR after second-guessing D. I share your skepticism, but now I think perhaps we are making a big assumption that Sarah would be FOR restriction IF she accepts Liang's premise that violent content leads to more aggression. We don't know what she would think under a different set of beliefs. So she has no opinion on C. Maybe she is a libertarian who is opposed to restrictions of any kind!
